| ) |
Send an L2CAP Connection Parameter Update request from the slave to the master.
- Note:
- An EVT_BLUE_L2CAP_CONN_UPD_RESP event will be raised when the master will respond to the request (accepts or rejects).
- Parameters:
-
conn_handle Connection handle on which the connection parameter update request has to be sent. interval_min Defines minimum value for the connection event interval in the following manner: connIntervalMin = interval_min x 1.25ms interval_max Defines maximum value for the connection event interval in the following manner: connIntervalMax = interval_max x 1.25ms slave_latency Defines the slave latency parameter (number of connection events that can be skipped). timeout_multiplier Defines connection timeout parameter in the following manner: timeout_multiplier x 10ms.
- Returns:
- Value indicating success or error code.

| ) |
Accept or reject a connection update.
- Note:
- This command should be sent in response to a EVT_BLUE_L2CAP_CONN_UPD_REQ event from the controller. The accept parameter has to be set if the connection parameters given in the event are acceptable.
- Parameters:
-
conn_handle Handle received in EVT_BLUE_L2CAP_CONN_UPD_REQ event. interval_min interval_max slave_latency timeout_multiplier id accept
